Experimental investigation on zero-Ø<Subscript>eff</Subscript> gaps of photonic crystals containing single-negative materials

Zhang, Liwei; Zhang, Yewen; He, Li; Li, Hongqing; Chen, Hong - In: The European Physical Journal B - Condensed Matter and … 62 (2008) 1, pp. 1-6

Epsilon-negative (ENG) and mu-negative (MNG) materials are successfully realized by using composite right/left-handed transmission line (CRLH TL), based on which the photonic crystals were also constituted. The simulated and measured scattering parameters and phase shift indicate that the...

First-principles investigation of electronic and optical properties in wurtzite Zn<Subscript>1-x</Subscript>Mg<Subscript>x</Subscript>O

Zhang, X. D.; Guo, M. L.; Liu, C. L.; Zhang, L. A.; … - In: The European Physical Journal B - Condensed Matter and … 62 (2008) 4, pp. 417-421

A first-principles study has been performed to evaluate the electronic and optical properties of wurtzite Zn<Subscript>1-x</Subscript>Mg<Subscript>x</Subscript>O. Substitutional doping is considered with Mg concentrations of x=0, 0.0625, 0.125, 0.1875 and 0.25, respectively. Mg incorporation can induce band gap widening due to the decrease...</subscript></subscript>

Single-oscillator model and determination of optical constants of spray pyrolyzed amorphous SnO<Subscript>2</Subscript> thin films

Caglar, Y.; Ilican, S.; Caglar, M. - In: The European Physical Journal B - Condensed Matter and … 58 (2007) 3, pp. 251-256

Amorphous SnO<Subscript>2</Subscript> thin films have been deposited using different spraying times via the spray pyrolysis method. The structure of the films was analyzed by X-ray diffraction and the results obtained showed that the structure of the films was almost non-crystalline. The optical properties of these...</subscript>

Intrinsic optical bistability in Kerr ferroelectric materials

Ibrahim, A. -B.M.A.; Osman, J. - In: The European Physical Journal B - Condensed Matter and … 63 (2008) 2, pp. 193-198

In this paper we investigate the intrinsic optical bistability (IOB) in a ferroelectric (FE) single layer using an alternative analysis. The FE material is considered to have an intensity-dependent refractive index where the third order nonlinear susceptibility χ<Superscript>(3)</Superscript> acts like Kerr coefficient....</superscript>
